Solution to Richard Tuckers Original Rolling-Block Maze:

The solution takes 39 moves. For the first move, you tip the block to the west. It now lies horizontally across two squares, so I put a number 1 in each of those two squares. For the second move, you roll the block to the north. It again lies horizontally across two squares, so a 2 is in each of those squares. For the third move, you roll the block east. It now stands upright on a single square, and that square has a (3) in it. I use parentheses to indicate when the block is upright. You dont really need that information, but its helpful.

At one point there is an alternate path you may have taken if you solved the maze. The alternate path is slightly longerby two moves. It starts with the block horizontal across the two squares numbered 22 then it precedes south, west, north, north, east, east, south, west, south. Weve now rejoined the main solution, and the block is standing upright on the square with (29) in it. At first I thought this alternate path was the only solution, and thats the solution I presented in Mensa Bulletin. Three readers, Rodney Hamilton, William Bradley, and Richard Horvitz, wrote me to point out a shorter path. So their path is now the official solution.
